Передача данных между классами в tkinter ⇐ Python

[Anonymous]

Я пытаюсь создать приложение, которое анализирует данные Excel, а затем печатает результат в сетке tkinter на экране. При выборе «Отчет1» в строке меню я не попадаю к «Отчет1» в классе HomeFrame, где я планировал создать отчет, а затем распечатать результат. Как мне это сделать?
